Seil 18

Designed by François Vivier

Seil is a large pram, 5.50 m long and 1.64 m wide, first drawn for a group of sailors near Nantes who wanted a sail and oar boat for the Loire and other rivers. The Scandinavian pram shape, clinker built with a small bow transom, makes her stable and seaworthy, and she can carry a crew of up to six, which suits families, sailing schools and youth groups.

She sets a tall standing lug and has two rowing thwarts. The designer describes the wooden version as particularly easy to build because the 9 mm plywood planks are few and have no twist. Seil 18 is the latest version, with side seats, floorboards that can be raised to sleep aboard under a tent, and an aft locker for a small outboard.
